79% of Internet users have clicked on an ad
More than half of US consumers with Internet access use social networking services, and penetration will continue to grow. Consumers are also spending ever-greater amounts of time on SNS, a fact that has advertisers drooling over the opportunity represented by SNS. IDC found that consumers who use SNS also tend to visit the services often and spend a lot of time per visit. More than three quarters of SNS users visit at least once a week, and no less than 57% visit at least once a day. During each session, 61% of SNS users spend at least 30 minutes on the respective site or stay logged in permanently, and 38% spend at least one full hour per session (or stay logged in). There are four major reasons why consumers use SNS: to connect and communicate; in response to peer-pressure; for entertainment; and for work-related purposes. Advertising does not factor into consumer motivations. In fact, users are less tolerant of SNA advertising than the best tolerated forms of online advertising. Ads on SNS have lower click-through rates than traditional online ads (on the Web at large, 79% of all users clicked on at least one ad in the past year, whereas only 57% of SNS users did), and they also lead to fewer purchases (Web: 23%; SNS 11%).
